UNITED STATES LOUIS J. VAN GUELPEN, OF CINCINNATI, OHIO.

SHOE-RELASTING MACHINE.

Application filed July 22,

To all whom it may concern:

Be it known that I, LOUIS J. VAN GUEL- PEN, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Shoe-Relasting Machines, of which the following is a specification.

My invention relates to new and useful improvements in means for lasting shoes, and it is more particularly directed to the provision of a machine for performing the second lasting operation on what is known as turned shoes, such shoes being lasted and stitched inside out, and then turned and subjected to a second lasting operation to impart their final shape thereto.

It is primarily the object of my invention to provide a'machine whereby a shoe may be snugly fitted on the forward portion of the last in a most rapid and efiicient manner, and without making unusual demands on the strength of the operator in contradistinction to the manual operation now employed of pounding the last against a table or other support to effect a snug engage ment of the shoe thereon.

A further object of my invention is to provide a means for inserting a shoe on a last which does not require pounding of the last, with the consequent damage entailed thereby.

A still further object resides in the provision of a lasting machine adapted to per form the functions above set forth and which has its parts so arranged as to most readily receive a shoe and last for the operation of the machine, to procure economy of the operators time and permit a most rapid operation of the machine.

With the above and other objects and advantages in View, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts as hereinafter more particularly described and defined. by the appended claims, and it may be stated here that my present invention is an improvement on the invention shown, described and claimed in United States Letters Patent No. 1,312,67 6, dated August 12, 1919.

In the accompanying drawing forming part of this specification:

when certain kinds of shoes are relasted,

parts broken away, and

Fig. 7, is an end View of the parts shown in Fig. 6, parts broken away.

In the drawing the character 1 represents 3 a table or support to which my machine is secured. I use a base and peculiarly shaped casting or frame made integral in the present instance and composed of a base 2, an upwardly and backwardly extending arm 3, a forwardly and upwardly extending arm t united by a curved connecting element 5, the curved top face of which forms a cam race 6; at the top of arm 3, I form a toe pad 7. The above parts are usually all formed integral.

On the top of the toe pad-7, I place a leather cushion 8 held on and in place by the rivets 9.

At the forward and lower portion of the arm 4 I loosely connect at point 10, a lever 12, and at the upper extremity of this lever I pivotally connectthe jaw members 1-3 and 14, at pivotal point 15. To the forward portion of the lever 12, I connect a pull-rod arm 16, which at its forward end has pivoted thereto the pull rod 17; this rod 17 ex tends downwardly to be connected to any suitable foot treadle, (not shown). At the inner side of the lever 12, I connect one end of a spring 18, which at its other end is connected to arm 3, at the point 19.

On the opposite side of the arm 4, near the top, I place the bearing lugs 20 and 21 made integral with arm 4-. Through these lugs I place the shaft 22, which shaft is slidable and oscillates. Between the lugs 20 and 21 on the shaft 22, at point 23, I rigidly connect the peculiarly shaped arm 24, shaped as shown, and at the back of this arm, around part of the cam race in sec and the point 2'? oi arm 2%, (when the lever or arm 24 is in its upward position). autoinatically engages in said slot 26, byreason of the push spring 25, operating to push said lever 24 into said slot when thesaid slot is reached as the lever is oscillated. At the top of arm or lever 2 l=ll place a grooved or cup shaped heel support 28, which has, at its extreme top a cover'or stop plate 29. Atthe bottom of said arm P l'l place a stop lug-"30, which limits thatsidewise movement or motion of said arm 24.

In the arms, I place a number of adjustingiholes 31 in which I place a stop pin'32, which stops the movement or" the lever 12' at the desired point.

At" the lower portion or end of themovable clamping jaw member it, I connect a ball weight 33 ,'pivoted at point 3%, in the jaw member 13.- V Thetup'per portion of the jaw memher 1% is an eccentric, as shown point 85, inFigsT1 and 4; These-j aw memberslS-iandl are" each 'provided with a multiplicityofholding or gripping teethld The last is marked O' and the shoe 41'. The above d-escriptionand mechanism which refers to the jaws Band- 14" and their op eration is usuallyemployed with shoes on which the heel or seat is left nnsewed; when the heel 'or seatis also sewed, as is sometimes the oase,-I replace the awe with the-device shown in Figs; 6 and? In these figures I show a block-42 pivoted to the arm 12 at point 43'; the bloolt l2'bei'ng provided atthe" forward part with a lugvll. On the block 42 I place a'hook'or-"horn 440:5 a desirable shape and contour. The means just described" is for use with 1a shoe having the heel or seat also sewed, and when such means are used a hole is placed in the/heel oi? the insole which engages with'the -hook iaoperating, the heel support 28 isthrownto one side (to the left), as shown in 'Fi 2; the shoe is then placed "on the toe pad 7 the loose portion of the sole, atthe heel, is placed in between-the jaws 1 3 and let, the ball 33' being pulled towards the operator closing the jaws and looking or gripping the sole therein; the last 40 is then inserted into the shoe -41 and is pushed forward and lined up in the shoe the lever 24 is then thrown into an upright position asshown in 1 and 3; the operator then placeshis toot upon the treadle of the machine (not shown), and hy'giving a downward pressure pulls the lever 12 by m'e'ans'oi the connecting link 17 and the attached arm 16, forward, and this lever being fulcrumed l0 and the'jaws 13 and l i" being pivoted at 1-5, allows the: lug 11: to ride the-facet of Cam 5 andby reason of the-camiace bein curved; the? shoe is pulled onto the la'st by seame 1. being-pressed: forward;

and the jaws still holding the shoe sole, 2 line described which is approximately same as the line on the last arch; this pulling th shoe from the toe out, and thus not bind in the instep 01" the shoe on the instep oi b a I 1 the last, (as has hereto'lore been the opera t ionlthusgiving a proper and desired contour to the shoe, the same as pulling the shoe onthe toot. This cam face can be varied in contour to suit any shape of last. During this operationthe heel supportQS and the heel of the last have been in engagement to lie-ep'the last fromnioving with the shoe, that is, in a stationary position, while the shoe is being pulled onto the I last.

When the operator (has pulled the shoe onto the to the" desired point or extent, he then works out thewrinltles and shapes the toe of the shoe with his tools and then talres his foot off 'ofthe-treadle, the lever 12 then moves hackwardrup against the stop pin 82', by'reasonof the spring 18, carrying the .shoeand theulastwith-itpthe operator hen pus 19s the hallSS baokwardly and disengages the sole from the "jaws 13 and and then talesthe shoe: flOIllllllS machine, throws the leverQl l-to the left and continues the same operation with another shoe;

It will be noted-that I providea nun her of holes l so' that: the pin SQ'canbe in any otsuch holes so that different sizes of shoes can be more readily operated upon. Vihen sewedseat shoes are'being relasted on this machine,a hole is cutinto the centerot the seat or heel of the shoe, for engaging the horn or pin 14; this part replacingthe function oi the jaws '13 and 14 however the same operation of the machine is employed otherwise;

While I have described one specific means for carrying my invention into efiect, it will be understood that the same is capableof some modification without departing from the spirit and'principleo'f the invention as covered by the claims.

What I claim as new and my invention and. desireto secureby LettersPatent is:
